Description

Antenna device and electronic device comprising same

Various embodiments of the present disclosure relate to an electronic device, for example, to an electronic device including an antenna device.

With the development of electronic communication technology, electronic devices having various functions are emerging. These electronic devices generally have a convergence function for complexly performing one or more functions.

As the functional gap between manufacturers of electronic devices is remarkably reduced, in order to satisfy consumers' purchasing desires, the rigidity of electronic devices is increased, design aspects are strengthened, and efforts are made to slim down. As part of this trend, electronic devices efficiently secure an arrangement space for at least one antenna device that must be provided for communication among components, and at the same time prevent deterioration in radiation performance and race for excellent performance. are doing

According to various embodiments, the antenna device used in the electronic device has an Inverted-F Antenna (IFA) or monopole radiator as a basic structure, and the volume and number of antenna radiators mounted according to the frequency, bandwidth, and type of each service. can be decided. For example, although there are differences in frequency by region around the world, in general, the low band of 700 MHz to 900 MHz, the mid band of 1700 MHz to 2100 MHz, and the high frequency band of 2300 MHz to 2700 MHz (high band) is used as the main communication band. Alternatively, the electronic device may use frequencies for various wireless communication services such as Bluetooth (bloutooth), global navigation satellite system (GNSS), and Wi-Fi.

In order for an electronic device to satisfy all of the above-described communication bands in a limited antenna volume, it is difficult to actually secure the entire band with only one antenna. In order to overcome this problem, antennas of electronic devices are designed to be divided into several by bundling service bands having similar frequency bands.

The electronic device may include a metal member (eg, a metal bezel, etc.) having an external appearance. In this case, the electronic device may be designed by using a metal member as an antenna radiator instead of a separate antenna, unlike a case in which the exterior includes an injection molding made of a dielectric material. For example, when a metal bezel used for an edge of an electronic device is used as an antenna radiator, the main antenna radiator and at least one coupling antenna radiator may be designed for the antenna of the electronic device with a dielectric material interposed therebetween. In the electronic device, since an electrical gap is formed by the segment between the main antenna radiator and the coupling antenna radiator, resonance in a desired frequency band can be formed using the coupling antenna radiator.

However, when the user grips the electronic device and comes into contact with the segmented part of the antenna, the electronic device may have a problem in that the antenna's radiation performance is significantly deteriorated because the capacitance component of the segment is changed.

Various embodiments of the present disclosure may provide an apparatus and method for preventing radiation performance degradation due to a change in capacitance of a bezel part used as an antenna in an electronic device.

According to various embodiments of the present disclosure, in a method of operating an electronic device, at least a portion of a first surface, a second surface facing in a direction opposite to the first surface, and a space between the first surface and the second surface is surrounded forming a housing including a side surface and a first portion of the side surface, forming a first metal member including first and second ends and a second portion of the side surface, the first end of the first metal member forming forming a third portion of the side surface with a second metal member electrically insulated from the first metal member, adjacent to a second end of the first metal member, and forming a second metal member electrically insulated from the first metal member. an insulated third metal member, a communication circuit electrically connected to at least one of the first metal member, the second metal member, or the third metal member, and at least one ground member included in the housing An operation of detecting whether an external object has contacted at least one of the first metal member, the second metal member, or the third metal member by an electronic device comprising: based on at least a part of the detection result, and changing an electrical path between at least one of the first metal member, the second metal member, or the third metal member and the ground member.

According to various embodiments, when a change in capacitance of a bezel part (eg, a lower bezel part) used as a metal housing antenna is detected, a new resonance path is formed, thereby improving radiation performance degradation of the antenna.

According to various embodiments, when a contact between the main antenna included in the metal housing and the segment of the first coupling antenna is detected, the sub-ground for isolation of the second coupling antenna is opened from the main antenna. ) to create a resonant path using the second coupling antenna to improve the radiation performance degradation of the antenna.
